Introduction to BASIC...CATALOG and jcompile

     BASIC MY.BP TEST.SUB
      
     TEST.SUB
     BASIC_1.c
     Source file TEST.SUB compiled successfully

     CATALOG MY.BP TEST.SUB
      
     TEST.SUB
     Object TEST.SUB cataloged successfully
     Library $HOME\lib\lib0.dll rebuild okay

     jcompile test.b
      
     Warning: Variable DIV.AMT2 is never assigned!
     test.c

Compilation results in appearance of an object and executable files (sample for Windows):

     test.obj
     test.dll
     test.exe

See program information:

     jshow -c test
      
     Executable:          C:\r11\BATfiles\test.dll
                          jBC main() version 11.0 Thu Dec 06 23:35:34 2012
                          jBC main() source file unknown
     Executable (DUP!!):  C:\r11\BATfiles\test.exe
                          jBC main() version 11.0 Thu Dec 06 23:35:34 2012
                          jBC main() source file unknown

If the code is recompiled very often then it might happen that the older version of executable code still resides in shared memory and the result of changes wouldn't be seen immediately. In this case "-E" option of jcompile can be used to build executable only and not the shared library, e.g.:

     jcompile -E test.b

And then test.dll isn't created. The final compilation is of course to be done without "-E" option. Also - without shared library CHAIN statement might work not as expected and persistence of COMMON areas won't be supported.

See commands used by compiler:

     jcompile -v test.b
      
     cl /nologo /DWIN32 /MD /W2 /GR /EHa -c -IC:\TAFC\include -DJBC_OPTLEVEL2 test.c
     ...
     cl /nologo /DWIN32 /MD /W3 /GR /EHa /GF /Zi /F5000000 -D_LARGEFILE_SOURCE ...

Conditional compilation:

       V.VAR = 1
       CRT 'Version ':
    #ifdef VER1
       CRT V.VAR:
    #else
       CRT V.VAR + 1:
    #endif
       CRT ' finished'

     jcompile -DVER1 test.b
     test.c
      
     test
     Version 1 finished

     jcompile test.b
     test.c
      
     test
     Version 2 finished

To look at C code rather than to create executables "-S" option can be used (files test.c and test.j will be created for test.b source).

Full information about jcompile options - "jcompile -H".
